SIGNATURE-SUPPORT FOR BOOK-SEWING MACHINES.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application led December `30, 1903. Serial No. 187.114.

To ctZZ whom, t may concern:

Be it known that I, JOHN R. REYNOLDS, a citizen of the United States, residing at Hartford, county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Signature-Supports for Book-Sewing Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in the signature-carrying arm of booksewing machines, and has for its object to produce an improved, simple, and cheap construction whereby the position of the punches which form the perforations through which the sewing-needle passes may be readily and quickly adjusted to bring sets of stitches into any desired relation with respect to each other along the back of the book.

IVith this and other objects in view the invention consists in certain constructions and in certain parts, improvements, and combinations, as will be hereinafter fully described and then specifically pointed out in the claims hereunto appended.

In the accompanying drawings, which show a preferred embodiment of the invention, Figure l represents in side elevation a form of signature-carrying arm embodying the invention. Fig, 2 is a view of the construction shown in Fig. l with one of the side plates removed, certain parts being shown in section. Figisaplanview. Fig.4isan end elevation of the construction shown in Fig. l. Fig. 5 is a section on the line 5 5 of Fig. l, and Fig. 6 is a detail perspective view of one of the punch-guiding sections.

In the machine which has been selected to illustrate the invention a plurality of signature-carrying arms provided with punches is employed, these arms being mounted on a vertical spindle around which they are rotated to bring the signatures successively into sewing position.

Referring more specifically to the specific construction illustrated in the drawings, 1 indicates a supporting-spindle on which is #mounted a rotating hub 2 said hub being provided with a pair of disks 3 4, in Which the signature-carrying arms are mounted. .The particular means for supporting the spindle and for operating the hub are not necessary to an understanding of the present invention,

and are therefore not illustrated.

In the preferred form of the construction the signature-carrying arm comprises a pair of side plates 5 6 5 but the construction may be varied in this respect, if desired. These side plates are supported between the disks 3 and 4 in any suitable manner, so that the arm will be firmly held during the rotation of the carrying-hub. These side plates 5 6 are spaced apart, and in the preferred construction the devices hereinafter described are mounted between them.

The construction includes an actuator for the punches, to be hereinafter referred to, and in the preferred form of the construction this actuator will be mounted so as to receive a combined sliding and vertical-reciprocating movement. While the construction of the actuator may be varied, in the construction shown, which illustrates a preferred embodiment of the invention, this actuator consists of a bar 7, provided with cam-slots 8, which slots engage pins 9, mounted in the plates 5 6. The means for operating the actuator may be of any desired character. In the construction shown the operation of the actuator is effected by means of a gab-hook l0, which is given a reciprocating motion from any suitable part of the machine. This gab-hook is in a fixed position in the machine, and in the rotation of the spindle on which the arms are mounted the studs on the arms come successively into engagement with the gab-hook, which then operates the actuator. In the preferred construction a spring 1 l is employed to insure that the actuator is in proper position with respect to the gab-hook, so that the pin is in vertical alinement with the hook. In the preferred construction and as is usual the punches are arranged in pairs to provide entering and exit perforations for the thread. The construction by which the punches are mounted may be varied Within wide limits. In the construction shown, however, each pair of l ticular construction illustrated the blocks are f connected to the actuator by providing each of them with aA groove 13, said groove being engaged by a projection 14 on the bar. The punches (marked 15) may be secured to the carrier-block in any suitable manner-as, for instance, by means of screws 16.

The adjustment of the punches may be effected in any suitable manner. As shown, however, this adjustment is effected by means of the punch-guide. The construction of the punch-guide by which it is caused to effect the adjustment of the punches may be widely varied. As shown, however, the punch-guide comprises a plurality of independent sections 17, each section being pro-- vided with a pair of guiding perforations- 18 for its pair of punches., These sections 17 'are independently adjusted along the arm and are arranged to be held in their adjusted position. Means for eifecting this adjust# ment may be varied; but, as shown, the sections slide between the plates which com' prise the arm and are held in their adjusted position by means lof holding-screws 19, suit-` ably-threaded openings 2() being provided in the arm at desired points. The screws pass through these threaded openings 20 and through openings 21, formed in the shanks of the guides. In the best constructions these guide-sections will be provided with extended signature-supporting faces 22, which serve to entirely support the signature, and when the bar is intended to be used in a machine employing curved needles these guiding-sections will also preferably be provided with needle-raceways 23, these raceways being curved to'conform to the curve of the needle.

The operation of the construction will be readily understood.'A Fig. 1 shows three sets of punches, although it is to be understood that as many sets of punches may be employed as desired, these punches being shown in a certain adjustment. The construction illustrated in this figure provides for two adjustments of the guide nearest the spindle 1 and for three adjustments of the guide next to it; but other adjustments are of course possible. By simply removing the screws, sliding the sections alonguntil the holes 21 in their shanks come opposite the proper holes in the support, and then reinserting the screws the desired adjustment is effected, the movement of the guide-sections carrying the punches and their carriers with them.

While the specific construction illustrated embodies the invention in its preferred form, it is to be understood that the invention may be embodied in constructions which differ therefrom. The invention is not, therefore, to be limited to the specific construction hereshown and described.
